Implement the seal water system of blast furnace gas in distributor of the present utility model, there is following beneficial effect:
Water coolant in the utility model cooling channel, behind discrete posticum and continuous effluent hole, can form cascade to intercept inner blast furnace gas between housing and water outlet plate, significantly improves the sealing effectiveness of blast furnace gas.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the seal water system of blast furnace gas in the utility model distributor;
Fig. 2 is the part sectioned view of water outlet plate.
Embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
Be illustrated in figure 1 the seal water system of blast furnace gas in distributor of the present utility model.Distributor comprises housing 2 and is arranged on the rotary barrel 12 in housing 2.
Seal water system comprises cooling channel 13, water outlet plate 6 and lower flume 9.Cooling channel 13 is fixed on the outside of rotary barrel 12, the outside of lower flume 9 stationary housings 2, and cooling channel 13 is positioned at top, and lower flume 9 is positioned at bottom.Water in cooling channel 13 flows in lower flume 9 by water outlet plate 6.Water outlet plate 6 is horizontally disposed with, and the entrance end of water outlet plate 6 is connected with cooling channel 13.The exit end of water outlet plate 6 above lower flume 9 and and housing 2 between gapped.
As shown in Figure 2, water outlet plate 6 inside are provided with annular continuous effluent hole 11 and spaced discrete posticum 10, and a plurality of discrete posticums 10 are also ring-shaped distributed.Between discrete posticum 10 and continuous effluent hole 11, be the trumpet-like transition region of convergent, the aperture in the aperture ratio continuous effluent hole 11 of discrete posticum 10 is large.Through discrete posticum 10, from continuous effluent hole, 11 outflows form continuous cascade 7 to water coolant in cooling channel 13, can between housing 2 and water outlet plate 6, form cascade 7 to intercept inner blast furnace gas, significantly improve the sealing effectiveness of blast furnace gas.
Further, seal water system also comprises centering wheel 1, the centering that is circumferentially with of rotary barrel 12 takes turns 1, gapped a between centering wheel 1 and housing 2, the characteristic of expanding with heat and contract with cold of gap a consideration material is determined, by the increase scope of rocking that wheel 1 can limit rotary barrel 12 of feeling relieved, the stability of distributor rotary barrel 12 strengthens greatly.Centering wheel 1 operated by rotary motion has four or six, is evenly distributed on the outside of rotary barrel 12.Because the stability of rotary barrel 12 strengthens greatly, the minimum clearance d of existing labyrinth seal 14 also can reduce greatly, and the effect of labyrinth seal 14 also significantly improves.
Further, the diameter of discrete posticum 10 is 18-22mm, and the diameter in continuous effluent hole 11 is 12-15mm, can form the cascade 7 of thinner thickness.
Further, the top of water outlet plate 6 is provided with the first baffle plate 3 of level, and the outside of housing 2 is provided with vertical second baffle 4, gapped b between second baffle 4 and the first baffle plate 3, and the first baffle plate 3, second baffle 4 and water outlet plate 6 form cooling water buffer district 5.Gap b is slightly larger than the gap between centering wheel 1 and housing 2.Can be under normal circumstances, distributor inside intercepts blast furnace gas by passing into nitrogen formation pressure-fired, and distributor internal pressure is a little more than furnace pressure, and now the nitrogen of distributor inside enters in blast furnace after can blowing one's water breaks curtain 7.In stove, produce pressure surge, furnace pressure is during higher than the pressure of distributor inside, and blast furnace gas also can blow one's water breaks curtain 7, and now the cooling water buffer district 5 of sealing can store the water coolant splashing after blast furnace coal air-blowing one's water breaks curtain 7 relatively.The volume in cooling water buffer district 5 can hold all water coolants that splash before the new nominal situation of formation, to guarantee that water coolant does not enter distributor inside.
Further, for preventing the water coolant impact to housing 2 sidewalls for a long time, the sidewall of housing 2 is provided with L-type plate 8, and the horizontal section of L-type plate 8 is positioned at water outlet plate 6 belows, and the gap that itself and water outlet plate are 6 is c, the vertical section of exit end facing to water outlet plate 6 of L-type plate 8.Due to the enhancing of centering wheel 1 rear cylinder body stability being set, gap c also can reduce greatly, therefore water coolant flows into lower flume 9 by this gap after flow out in the continuous effluent hole 11 on water outlet plate 6, will form the cascade 7 of thinner thickness to intercept blast furnace gas in this gap area.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
